Realizing in-situ magnetic phase transition in metallic van-der-Waals magnet Fe5GeTe2 via ultra-high charge doping A RMIT-led international collaboration published this week has achieved record-high electron doping in a layered ferromagnet, causing magnetic phase transition with significant promise for future electronics Control of magnetism (or spin directions) by electric voltage is vital for developing future, low-energy high-speed nano-electronic and spintronic devices, …
Congratulations to two of FLEET’s Chief Investigators, whose contributions have recently been recognised by the School of Physics and Astronomy at Monash University: Meera Parish promoted to full Professor Agustin Schiffrin promoted to Associate Professor Prof Meera Parish (right) is a theoretical physicist developing many-body theories that span electron-hole systems and ultracold atomic gases. She is an ARC Future Fellow …
Controlling Dzyaloshinskii-Moriya interaction (DMI) in chiral magnet iron-doped tantalum-sulfide by proton intercalation Magnetic-spin interactions that allow spin-manipulation by electrical control allow potential applications in energy-efficient spintronic devices. An antisymmetric exchange known as Dzyaloshinskii-Moriya interactions (DMI) is vital to form various chiral spin textures, such as skyrmions, and permits their potential application in energy-efficient spintronic devices. Published this week, a Chinese-Australia …
How does global research collaboration work, while Covid-19 still prevents international in-lab visits? A recent FLEET collaboration found a creative solution, running in-lab demonstrations of new quantum technologies across multiple universities on two continents. FLEET’s Matthias Wurdack (ANU) and Semonti Bhattacharyya (Monash) were able to consult with researchers in the New York lab of FLEET PI Jim Hone (Columbia University), …
Great results for STEM in Australian universities in the Shanghai/ARWU 2021 rankings, with Australian universities represented in the world top-100 for all the natural sciences and engineering disciplines except maths. Highlights amongst FLEET’s participating nodes include: Monash and ANU (#28) ranked in the global top 100 for physics UNSW top 40 for electronic engineering Monash, UOW, UNSW and UQ top 100 for material …
What is the future of computing? As Moore’s law is approaching an end, new technologies are required to enable further advances in computational speed and energy-efficient data processing. As transistors took their first baby-steps over half a century ago, the next generation of electronic switches are being born today. Engaging with the Melbourne computing and electronics community in a ‘fireside …
Please welcome FLEET’s three new Women in FLEET Honours students: Kyla Rutherford (RMIT) Olivia Kong (UNSW) Robin Hu (ANU) Kyla, Olivia and Robin have all received Women in FLEET Honours Scholarships, which are awarded to high performing students doing their Honours research project with FLEET. Kyla Rutherford will be working with Jared Cole at RMIT to understand transport properties in …
X- ray photoelectron spectroscopy (XPS) is used for material characterization, providing quantitative information on the chemical composition of materials by identifying the type of elements that are present (nowadays, with a detection limit in the range of one part per thousand). XPS also allows the identification of the chemical state of the elements – such as the types of bonds …
An exotic class of topological quantum materials has been reviewed by an international team of physicists, led by A/Prof Bent Weber at Nanyang Technological University (NTU – Singapore). Atomically-thin quantum spin Hall insulators, whose electronic states are protected by topology, promise applications in quantum information processing. Quantum spin Hall insulators are a class of two-dimensional (2D) topological states of matter …
A ‘pumped’ laser can be used to trap and manipulate an exciton-polariton condensate. These quantum fluids, which can behave as a resistanceless superfluid in certain conditions, need continuous replenishing, with the pumping laser supplying both a reservoir of electrons and confining force. “The pumping laser can trap the quantum fluid as the particles are repelled from the pump region, similarly …
Melbourne Knowledge Week (26 April-2 May 2021) was an opportunity for FLEET to engage with over 350 members of the public about the exciting future of computing, and the vital role of energy-efficient electronics in that future. FLEET’s sustainable computing booth ran for the full week at the festival hub, with hands-on science demonstrations linked to materials used in FLEET …
FLEET had four researchers at STA’s annual Science Meets Parliament, which was fully online in 2021, other than regional gala dinners. Participants heard from a diverse mix of Australia’s top scientists, including Chief Scientist Cathy Foley and Chief Defence Scientist Tanya Monro. FLEET’s four ECR delegates—Eli Estrecho (ANU), Peggy (Qi) Zhang (UNSW), Gary Beane (Monash) and Harley Scammell (UNSW)—were introduced …
US–Australian transpacific condensed-matter talks The temporary halt in international visits that traditionally spark and fuel research collaborations in 2020 pushed FLEET to find new ways to connect. Some positives have surfaced amid the negative impacts of Covid-19 travel bans on science collaboration, including the expansion in videoconferencing allowing researchers from geographically isolated regions to connect. Together with Centre partners at …
FLEET is building links with partners interested in novel electronic devices and systems working towards the overarching goal of creating pathways to translations of research outcomes. Progress towards this important goal in 2020 included: Adding topological transistors to the Institute of Electrical and Electronics Engineers (IEEE) International Roadmap for Devices and Systems Lodging two provisional patents: topological switching (Fuhrer Monash and …
Two patent applications, one filed in 2020, reinforce FLEET’s position as a world leader in topological transistors. The patents cover work in the ‘switching’ of topological material, to facilitate creation of a functioning topological transistor – a proposed new generation of ultra-low energy electronic devices. Their world-first success was the switching of a material via application of an electric-field between …
